Abstract
A method and a device for cancelling transmitter interference in a transceiver, and a transceiver are provided. The method includes: coupling a part of radio frequency signals output from a transmitter, performing amplification, frequency conversion, analog-digital conversion, and digital filtration on the coupled signal by an interference receiver, and outputting a digital signal; performing adaptive equalization on the digital signal output from the interference receiver, and delaying predetermined time of the digital signal output from a receiver, and subtracting the equalized digital signal from the delayed digital signal.
